Thermalright Shaman VGA Cooler Tested on a GTX 480 with FurMark

The Shaman VGA cooler has been able to reduce the GPU temperature by 10°C in a nearly noiseless way. Cool! But this result is far from Thermalright’s SpitFire: the temperature of the GTX 480 GPU does not exceed 66°C with FurMark… Did I miss something?
